“ The experience of yearning is a composite of Nature’s purest impulse in you (the need for radical movement; think of all the analogies in all the religions and philosophies concerning the truth and beauty of light; if you take it literally, that means to become truth, beauty, light, get moving at 299,792,458 kilometres per second) combined with your unique qualities and talents of past/present/future (experiences, potentials, attractions and distractions, imagination, etc.). Simply put: need for radical movement in a definite direction. ”
